Identification and phytoremediation potential of spontaneous species in vineyard soils contaminated with copper

Abstract

Copper (Cu) contents in vineyard soils due to the application of cupric fungicides cause changes in the native covering flora. Under these conditions, the surviving individuals accumulate the metal in and decrease its availability in the soil, reducing the potential toxicity to grapevine. We have identified spontaneous plant species and their phytoremediation potential from vineyards of Isabella (Vitis labrusca) on two distinct soil types (Inceptisol and Entisol) contaminated with Cu. The results demonstrated that wild species displayed higher Cu contents in the roots than in the shoot, but had low bioaccumulation potential. During summer, the plants were unable to extract and stabilize the metal, although during the winter, Lolium multiflorum, Cyperus compressus and Chrysanthemum leucanthemum demonstrated phytostabilization potential. Among the investigated species, dry matter production and Cu accumulation by Lolium multiflorum indicated that the species is effective to decrease Cu availability in the soil.

A meta-analysis on the heavy metal uptake in Amaranthus species

“…Several hundred weeds have been proven to be good candidates for phytoremediation purposes due to their ability to decrease metal concentration in soil; these species are stress-tolerant, usually with fast growth and biomass production enabling even in a wide variety of environments (Tőzsér et al 2019 ; Alizadeh et al 2021 ; Melo et al 2022 ). These characteristics can also be observed in several Amaranthus species.…”

Removal Of Environmental Pollutants (Lead, Chromium And Cadmium) Using Root And Leaf Tissues Of Indian Mustard, Rice And Wheat Plants

“…are some plants which were capable of eliminating heavy metals. Moreover, other plants were also used to remove different contaminants (Ampiah-Bonney et al, 2007; Maine et al, 2021; Melo et al, 2021; Pratas et al, 2012).…”
